Here's a taster:

What is meant by behaviour?
· Behaviour is described as the response of an
organism to its environment which increases
its chances of survival.
· Innate behaviour is any animal response that
occurs without the need for learning. It is an
inherited response, similar in all members of
the same species and is always performed in
the same way in response to the same
stimulus.…read more

Here's a taster:

2.4.11 Innate behaviour
· Genetically determined so the environment
has no impact on behavioural response.
· Rigid and inflexible.
· Patterns of behaviour are the same
(stereotypical) in all members of a species.
· Unintelligent in the sense that the organism
probably has no sense of the purpose of the
behaviour.…read more

Here's a taster:

2.4.11 Learned behaviour
· Determined by the relationship between the
genetic make up of the individual and
environmental influences. Not passed on to
offspring via reproduction but may be via
teaching.
· Can be altered by experience
· Considerable variety is shown between
members of a species
· Learned behaviours form the basis of all
intelligent and intellectual activity.…read more

Here's a taster:

2.4.11
· Invertebrates rely for their survival on 3 types
of innate behaviour. These behaviours allow
them to escape predators, locate and stay in a
suitable habitat, and locate food.
· Invertebrates have short life spans, live
solitary lives and do not take care of offspring,
this means that innate behaviours are more
suitable as survival mechanisms than learned
behaviours.…read more

Here's a taster:

2.4.11
· Reflexes: Invertebrates have an escape reflex, to avoid
predators. Escape reflexes are involuntary responses
which follow a specific pattern in response to a given
stimulus.
· A kinesis is orientation behaviour where the rate of
movement increases when the organism is in
unfavourable conditions. The behaviour is non-
directional, meaning that the response is to change
the rate of movement overall.
· E.g. woodlice live in damp, dark areas to avoid
predation, so when placed in dry/bright conditions
they will move around rapidly and randomly until they
are in more suitable conditions where they will either
slow down or stop moving altogether.…read more
